CHARLES M. KIMBALL, OF TOLEDO, OHIO, ASSIGNOR TO HIMSELF AND JOHN M. WHEELER, OF SAME PLACE.

TO P.

SPECIFICATION forming part of Letters Patent No. 272,707, dated February 20, 1883.

Application filed July 7, 1882. (No model.) 7

To all whom it may concern.-

Be it known that, I, CHARLES M. KIMBALL, of Toledo, in the county of Lucas and State of Ohio, have invented certain improvements in Tops, of which the following is a specification.

This invention has for its object to provide an improved toy, adapted to subserve, also, a useful purpose as a lung testing or exercising apparatus.

To thisend the invention consists, asa whole, in a top adapted to be rotated by the pressure of air or other fluid or vapor, a support or step for the spindle of the top, and one or more ports or passages in a structure or base supporting the step, said passages being adapted to direct jets of air or other fluid, as vapor or gas, against the top, so as to rotate the latter, as I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figure i represents a top'view of a toy or apparatus embodying my invention. Fig. 2 represents a vertical section of the same on line 00 a: of Fig. 1.

The same letters of reference indicate the same parts in all the figures.

In carrying out my invention I provide a top, A, composed of a suitable spindle and a wheel aflixed to the spindle, and having oblique blades a, or otherwise constructed, so that it will be rotated by fluid-pressure against either ofits sides. I also provide a conca\e recessed step, B, adapted to support the lower end of the top-spindle and prevent the top from moving away laterally While rotating. The step B is supported on a base, 0, in which is a chamber, 1).

E E represent ports or small orifices in the base U, communicating with the chamber D, and so located with relation to the step B that they will direct jets of air or other fluid from the chamber D against the side of the Wheel of the top, as indicated by arrows in Fig. 2, thereby rotating the top. Before the top acquires'sufflcient momentum to enable it to stand the upper end of its spindle should be supported by a removable device, F, as shown in dotted lines in Fig. 2, said device being prefports E E. The top is preferably operated by air blown from the lungs, a flexible or rigid tube, J, being provided, through which the operator can blow into the chamber D. The

lungs are thus usefully exercised. If desired,

the chamber D may contain water, and steam may be generated therefrom to operate the top.

I do not limit myself to any particular number of ports E. as one or more may he em-,

ployed. If desired, the ports may he arranged to direct the fluid downwardly upon the wheel of the top, instead of upwardly.

I claim- 1. A lung testing and exercising apparatus composed of a top adapted to be operated by air-pressure, and means for directing air from the lungs against said top, as set forth.

2. The method herein described of spinning or operating a top, consisting in placing the spindle of the top on a suitable step or support and directing a jet or jets of a suitable fluid under pressure against the top, so as to rotate the latter, as set forth.

3. As an article of manufacture, a top composed of a spindle and a wheel attached to the spindle, and adapted to be operated by pressure of air or other fluid, as set forth.

4. The improved toy, composed of a. top adapted to be rotated by fluid or vaporic pressure, a support or step for the spindle of the top. and one or more ports or passages adapted to direct a fluid under pressure against one or more points on the top, and thereby rotate the same, as set lorth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, this 3d day ofJuly, 1852.

CHAS. M. KIMBALL.
